can you get rid of "noise"?

Can you get rid of "noise" if a pic is shot with too high of an ISO? and if so how is the best way? I have photo shop and also the pics are in RAW form. Thank you in advance for the tips!!!

One way of reducing noise is by using the "Median filter" in Photoshop.

Filter > Noise > Median

This is best done by applying the filter to each individual channel R/G/B
or you could just try it on the entire image OR just check the individual channels and apply only top the noisy ones.

I would make a duplicate of the image and work on that so you always have the original no matter what.

1) selest the Red channel apply Median filter setting of 1 (this is vital)
2) select Green channel same as above
3) select Blue and same as above.

best thing is to experiment and see if just applying to one or two channels does the trick. I find this technique sometimes better than others BUT it will soften the image a little.

I use Neat Image and find that is very good to use, you can down load the Demo but your limited to what you can do with it, here the link http://www.neatimage.c​om/download.html

A quick and easy way to get rid of the little green and red flecks of noise (also called "chroma - meaning color - noise", or "color gremlins") is to use the Median filter, but not in the complicated way mentioned in the post above.

Here is an EASY and EFFECTIVE way:

1 Duplicate the layer
2 Apply the Median filter to the top layer - it will ask you for a number. Use the same number as the number of mega-pixels as your camera. So with one of my 10D pictures I use 6.
3 Change the blend mode of that layer to "Color"
4 Say B-Bye to the Gremlins and Flatten.

Other way to reduce noise in row is in the detail tab increase the luminance smoothing to 40 and reduce color noise to 15, play with this two control

thank you so much for the tips. I will be trying all of them tonight
